What the vulnerability is
Node.js's experimental Permission Model evaluates wildcard filesystem access patterns through a radix tree lookup that, in certain cases, grants broader filesystem access than the pattern was intended to allow.
Why you should pay attention
Applications that use the Permission Model specifically to restrict a process's filesystem access to a narrow, intended set of paths can end up with wider access than configured, undermining the sandboxing the Permission Model is meant to provide. This matters most for deployments that treat the Permission Model as a hard security boundary rather than a defense-in-depth measure.
